Welcome aboard. I'm a new commuter too, started on the 20th of January with a plan to ride four days a week. Some days I ride two, some three, some four but I find that my days are better when I have started it on my bike. I'm wide awake, after the ride to work, hydrated and ready to work. At the end of the day I can unwind on the ride home. Go hard and fast or slower and longer if I want to and arrive feeling good. I sleep better on the nights when I have been riding, I and eat a bit more and still lose some weight, there are few down sides to riding a bike to and from work. Enjoy the ride!
